Rubber member sticking device

ABSTRACT

Provided is a rubber member sticking device which prevents a sheet material held from becoming deformed and stretching during a separation operation, thus suppressing loss of energy and eliminating traces of vacuum holes. When an unvulcanized rubber sheet  12  is stuck, the unvulcanized rubber sheet  12  is supported by a separating surface  14 A of a flat plate  14  and fitting surfaces  19 A of a lifting member  16  without a difference in level being created therebetween. In this state, the unvulcanized rubber sheet  12  is in close contact with the fitting surfaces  19 A of the lifting member  16 . When the unvulcanized rubber sheet  12  is separated, a hydraulic jack  20  lowers the lifting member  16  to create a difference in level between the separating surface  14 A of the flat plate  14  and the fitting surfaces  19 A of the lifting member  16  so that the unvulcanized rubber sheet  12  is supported only by the separating surface  14 A of the flat plate  14 . Thus, the unvulcanized rubber sheet  12  can be easily separated, and deformation and stretching of the unvulcanized rubber sheet  12  during a separation operation can thereby be suppressed.

TECHNICAL FIELD

The present invention relates to a rubber member sticking device.

BACKGROUND ART

As shown in FIGS. 10 to 13, a rubber member sticking device 100/106, inwhich a flat plate 104/cylindrical body 108 handles a viscous sheetmaterial 102, is used as a device for holding and transferring a viscoussheet material such as an unvulcanized rubber sheet.

A method is known wherein, when a viscous sheet material 102 is held bya rubber member sticking device 100/106, the viscous sheet material 102is stuck on a flat plate 104/cylindrical body 108 which has a goodadhesion compatibility with the viscous sheet material 102, and then,when the viscous sheet material 102 is transferred, force is appliedthereon so that the viscous sheet material 102 is separated from theflat plate 104/cylindrical body 108. However, in this method, as shownin FIGS. 11 and 13, depending on the extensibility of the viscous sheetmaterial 102, the viscous sheet material 102 may become deformed andstretch by virtue of a separation force.

Thus, a method has been adopted, wherein the viscous sheet material 102is held by means of the suction of a vacuum device, and the viscoussheet material 102 is then separated by means of a vacuum break or anair blow. However, when this method is used, loss of energy issubstantial and traces of vacuum holes of the vacuum device are leftbehind. In a case where the air blow method is utilized, air is blownbetween the flat plate 104/cylindrical body 108 and the viscous sheetmaterial 102 to separate them from each other, and there is thus also apossibility of the viscous sheet material 102 becoming deformed.

The present invention has been made in view of the above facts, andprovides a rubber member sticking device which prevents the viscoussheet material from becoming deformed and stretching during theseparation operation, suppresses loss of energy and eliminates traces ofvacuum holes.

DISCLOSURE OF THE INVENTION

A rubber member sticking device according to claim 1 of the presentinvention comprises: a first sheet receiving member including aseparating surface capable of releasing from a sheet material; a secondsheet receiving member including fitting surfaces capable of adhering tothe sheet material; and a driving means driving the first sheetreceiving member or the second sheet receiving member, such that, whenthe sheet material is stuck, the sheet material is supported by theseparating surface and the fitting surfaces without a difference inlevel being created therebetween, and, when the sheet material isseparated, the sheet material is supported only by the separatingsurface with a difference in level being created between the separatingsurface and the fitting surfaces; wherein the sheet material is a thinmaterial and includes, for example, a viscous sheet material such as anunvulcanized rubber sheet material for tires.

In the rubber member sticking device according to claim 1 of the presentinvention, when the sheet material is stuck, the sheet material issupported by the separating surface of the first sheet receiving memberand the fitting surfaces of the second sheet receiving member without adifference in level being created therebetween. In this state, the sheetmaterial is in close contact with the fitting surfaces of the secondsheet receiving member.

Accordingly, even when the rubber member sticking device is moved in avertical, longitudinal or widthwise direction, or rotated, the sheetmaterial is neither removed nor dislocated.

On the other hand, when the sheet material is separated, the drivingmeans drives the first sheet receiving member or the second sheetreceiving member to create a difference in level between the separatingsurface of the first sheet receiving member and the fitting surfaces ofthe second sheet receiving member so that the sheet material issupported only by the separating surface of the first sheet receivingmember.

In this process, only portions of the sheet material supported by thefitting surfaces are released first in a state in which the remainingportions of the sheet material continue to be supported by theseparating surface. Therefore, deformation and stretching of the sheetmaterial occur only at portions thereof corresponding to the fittingsurfaces, and in this way wholesale deformation and stretching of thesheet material can be suppressed. Then, when the sheet material isseparated from the separating surface, because the separating surfacehas no adhesive property, the sheet material can be transferred andtransported with a modicum of force. Further, unlike the prior art, itis not necessary for the sheet material to be held by means of suctionof a vacuum device, and traces of vacuum holes of the vacuum device canthus be eliminated.

As described above, the rubber member sticking device according to thepresent invention produces a superior effect insofar that the sheetmaterial is prevented from becoming deformed and stretching during theseparation operation, loss of energy is suppressed and traces of vacuumholes are eliminated.

In the rubber member sticking device according to claim 2 of the presentinvention, which is based on the structure according to claim 1, asurface constituted of the separating surface and the fitting surfaces,for supporting the sheet material, is a flat surface.

In the rubber member sticking device according to claim 2 of the presentinvention, the sheet material is supported by the flat surface.

In this state, since the gravity of the sheet material acts directly onthe supporting surface, the sheet material can be held even when theadhesive force on the fitting surfaces of the second sheet receivingmember is relatively weak. When only a modest adhesive force is requiredfor settling the sheet material on the fitting surfaces, only a modestdriving force is required for separating the sheet material from thefitting surfaces, and in consequence the sheet material can be held andtransferred with a modicum of energy.

In the rubber member sticking device according to claim 3 of the presentinvention, which is based on the structure according to claim 1, asurface constituted of the separating surface and the fitting surfaces,for supporting the sheet material, is a cylindrical surface.

In the rubber member sticking device according to claim 3 of the presentinvention, the sheet material is supported by the cylindrical surface.

The sheet material supported by the cylindrical surface is capable ofrotating movement. A combination of the rotating movement and theseparation operation enables the sheet material to be transferredeasily.

In the rubber member sticking device according to claim 4 of the presentinvention, which is based on the structure according to claim 3, thesheet material is supported by a cylindrical body serving as a transferdrum for tires.

In the rubber member sticking device according to claim 4 of the presentinvention, since the sheet material is supported by the cylindrical bodyserving as a transfer drum for tires, the sheet material can betransferred easily. An unvulcanized rubber sheet material for tires ispreferably used as the sheet material.

In the rubber member sticking device according to claim 5 of the presentinvention, which is based on the structure according to any of claims 1to 4, the separating surface of the first sheet receiving member isprovided with a plurality of through-holes extending in a thicknessdirection of the first sheet receiving member, and the second sheetreceiving member is provided so as to fit into/retract from thethrough-holes, so that the sheet material is supported by the fittingsurfaces and the separating surface without a difference in level beingcreated therebetween.

In the rubber member sticking device according to claim 5 of the presentinvention, the sheet material is supported by the separating surface ofthe first sheet receiving member and the fitting surfaces of the secondsheet receiving member without a difference in level being createdtherebetween. In other words, when the sheet material is stuck, thesecond sheet receiving member is pushed outside through thethrough-holes of the first sheet receiving member so as not to create adifference in level between the fitting surfaces of the second sheetreceiving member and the separating surface of the first sheet receivingmember.

On the other hand, when the sheet material is separated, the secondsheet receiving member is pulled inside through the through-holes of thefirst sheet receiving member, and the sheet material is supported onlyby the separating surface of the first sheet receiving member.

This relatively simple structure, in which the second sheet receivingmember is provided so as to fit into/retract from the through-holes ofthe first sheet receiving member, provides the rubber member stickingdevice with plural surfaces to be fitted to the sheet material.

The plural fitting surfaces, where the sheet material and the secondsheet receiving member make contact with each other, enable the sheetmaterial to be held in a stable fashion. Further, since the forcerequired to hold the sheet material is dispersed and thus only arelatively small force is applied to each of the fitting surfaces, onlya relatively small force needs to be applied to each of the portions ofthe sheet material corresponding to the fitting surfaces during theseparation operation. Accordingly, deformation and stretching of thesheet material during the separation operation can be prevented withgreater certitude.

In the rubber member sticking device according to claim 6 of the presentinvention, which is based on the structure according to any of claims 1to 5, on a surface constituted of the separating surface and the fittingsurfaces for supporting the sheet material, the fitting surfaces arerespectively formed in a substantially V-shape in a plan view.

In the rubber member sticking device according to claim 6 of the presentinvention, the sheet material makes contact with the substantiallyV-shaped fitting surfaces on the supporting surface.

Since the fitting surfaces are respectively formed in a substantiallyV-shape and thus the fitting surfaces make close contact with the sheetmaterial at a certain angle to the widthwise direction of the sheetmaterial, the sheet material is easily separated from the fittingsurfaces.

In the rubber member sticking device according to claim 7 of the presentinvention, which is based on the structure according to any of claims 1to 4, the second sheet receiving member is provided at both end portionsof the first sheet receiving member such that, when the sheet materialis stuck, both end portions of the sheet material make contact with thefitting surfaces.

In the rubber member sticking device according to claim 7 of the presentinvention, both end portions of the sheet material make contact with thefitting surfaces of the second sheet receiving member.

The simple structure, in which both end portions of the sheet materialmake contact with the fitting surfaces of the second sheet receivingmember, enables the sheet material to be held in a stable fashion.

MOST PREFERRED EMBODIMENTS FOR IMPLEMENTING THE INVENTION

A first embodiment of a rubber member sticking device according to thepresent invention will be described with reference to the drawings.

As shown in FIG. 1, a rubber member sticking device 10 handles anunvulcanized rubber sheet 12 serving as a viscous sheet material.

The unvulcanized rubber sheet 12 will now be outlined.

As shown in FIG. 9, rubber 90 in an unvulcanized state, which is the rawmaterial for the unvulcanized rubber sheet 12 (see FIG. 1), is softenedby heat and supplied to an extruder 92. The extruder 92 extrudes therubber 90 in the unvulcanized state from a mouthpiece 92A. The extrudedrubber 90 in the unvulcanized state is cut into the unvulcanized rubbersheet 12. The unvulcanized rubber sheet 12 is held and transferred bythe rubber member sticking device 10.

As shown in FIGS. 1 and 2, the rubber member sticking device 10 includesa flat plate 14 serving as a first sheet receiving member, on which theunvulcanized rubber sheet 12 is disposed. The flat plate 14 may be madeof a material capable of releasing from the unvulcanized rubber sheet 12(e.g., Teflon®), or, alternatively, may be made of a material capable ofadhering to the unvulcanized rubber sheet 12 (e.g., iron) and thereaftersubjected to surface treatment (grain finish) so as to secure a releaseproperty. Since the unvulcanized rubber sheet 12 is supported by aseparating surface 14A of the flat plate 14, the unvulcanized rubbersheet 12 can be separated by means of a modicum of force.

The flat plate 14 is provided with plural rectangular through-holes 14B,which extend from the separating surface 14A in a thickness direction ofthe flat plate 14, and which are arranged in parallel with each other. Alifting member 16 serving as a second sheet receiving member is disposedbelow the through-holes 14B. The lifting member 16 is composed of arectangular base plate 17 and fitting blocks 19 provided atpredetermined intervals so as to protrude from an upper surface 17A ofthe base plate 17 and fit into the through-holes 14B. The height of thefitting blocks 19 is determined such that, when the fitting blocks 19fit into the through-holes 14B, and in consequence there is nodifference in level between fitting surfaces 19A of the fitting blocks19 and the separating surface 14A and a flat surface is thereby formed,the upper surface 17A of the base plate 17 abuts against a bottomsurface 14C of the flat plate 14. A capability of adhering to theunvulcanized rubber sheet 12 may be imparted to the fitting surfaces 19Aby using a material capable of adhering to the unvulcanized rubber sheet12 (e.g., iron) to make the fitting blocks 19 themselves, oralternatively, by subjecting the fitting blocks 19 to surface treatment.

The base plate 17 is supported by a rod 18 of a hydraulic jack 20. Whenthe rod 18 is lengthened or shortened, the lifting member 16 is raisedor lowered.

The hydraulic jack 20 is contained in a casing 22. An opening 22A of thecasing 22 is closed by the flat plate 14, and the lifting member 16 isaccommodated inside the casing 22.

Further, guide blocks 24 are mounted on four corners of a bottom plateof the casing 22. Recessed portions 24A are respectively formed in lowersurfaces of the guide blocks 24 to engage slidably with rails 26. Thisstructure enables the casing 22 to move in the direction of Arrow A.

Next, the operation of the first embodiment will be described.

As shown in FIG. 3, when the unvulcanized rubber sheet 12 is stuck, theunvulcanized rubber sheet 12 is supported by the separating surface 14Aof the flat plate 14 and the fitting surfaces 19A of the lifting member16 without a difference in level being created therebetween. In thisstate, the unvulcanized rubber sheet 12 is in close contact with thefitting surfaces 19A of the lifting member 16. Since the gravity of theunvulcanized rubber sheet 12 acts directly on the fitting surfaces 19A,the unvulcanized rubber sheet 12 can be reliably held even when theadhesive force on the fitting surfaces 19A of the lifting member 16 isrelatively weak. Further, the plural fitting surfaces 19A, where theunvulcanized rubber sheet 12 and the lifting member 16 make contact witheach other, enable the unvulcanized rubber sheet 12 to be held in astable fashion.

Accordingly, even when the rubber member sticking device 10 (see FIG. 1)is moved in a vertical, longitudinal or widthwise direction, theunvulcanized rubber sheet 12 is neither removed nor dislocated.

On the other hand, as shown in FIGS. 4 and 5, when the unvulcanizedrubber sheet 12 is separated, the hydraulic jack 20 lowers the liftingmember 16 to create a difference in level between the separating surface14A of the flat plate 14 and the fitting surfaces 19A of the liftingmember 16 so that the unvulcanized rubber sheet 12 is supported only bythe separating surface 14A of the flat plate 14.

In this process, only portions of the sheet material 12 supported by thefitting surfaces 19A are released first in a state in which theremaining portions of the sheet material 12 continue to be supported bythe separating surface 14A. Therefore, deformation and stretching of theunvulcanized rubber sheet 12 occur only at portions corresponding to thefitting surfaces 19A, and in this way wholesale deformation andstretching of the unvulcanized rubber sheet 12 can be suppressed. Sincethe fitting surfaces 19A are dispersed at plural portions, the adhesiveforce is also dispersed and only a relatively modest force needs to beapplied to each of the fitting surfaces 19A, to separate it from theunvulcanized rubber sheet 12. Deformation and stretching of theunvulcanized rubber sheet 12 can accordingly be prevented with greatercertitude.

Further, since the unvulcanized rubber sheet 12 is disposed on the flatsurface, only a relatively small adhesive force is required for settingthe unvulcanized rubber sheet 12 on the fitting surfaces 19A, andaccordingly only a relatively small driving force is required when theunvulcanized rubber sheet 12 is separated from the fitting surfaces 19A.In consequence, the unvulcanized rubber sheet 12 can be held andtransferred with a modicum of energy.

Furthermore, since the separating surface 14A has no adhesive property,when the unvulcanized rubber sheet 12 is separated from the separatingsurface 14A, the unvulcanized rubber sheet 12 can be transferred andtransported with a modicum of force.

In the present invention, unlike in the prior art, it is not necessaryfor the unvulcanized rubber sheet 12 to be held by means of suction of avacuum device, and traces of vacuum holes of the vacuum device can thusbe eliminated.

Next, a second embodiment will be described.

In the second embodiment, as shown in FIGS. 6 and 7, a rubber membersticking device 30 includes a drum 34 serving as a first sheet receivingmember, around which the unvulcanized rubber sheet 12 is wound. The drum34 may be made of a material capable of releasing from the unvulcanizedrubber sheet 12 (e.g., Teflon®), or, alternatively, may be made of amaterial capable of adhering to the unvulcanized rubber sheet 12 (e.g.,iron) and thereafter subjected to surface treatment (grain finish) so asto secure a release property. Since the unvulcanized rubber sheet 12 issupported by a separating surface 34A of the drum 34, the unvulcanizedrubber sheet 12 can be separated by means of a modicum of force.

The separating surface 34A is provided with plural substantiallyrectangular through-holes 34B arranged in parallel with each other.Corners of each through-hole 34B are rounded.

A lifting member 36 serving as a second sheet receiving member isdisposed inside the drum 34. The lifting member 36 is composed of baseplates 37 having circular-arc-shape in a sectional view and fittingblocks 39 provided so as to respectively protrude from the base plates37 in a radially outer direction and fit into the through-holes 34B. Theheight of the fitting blocks 39 is determined such that, when thefitting blocks 39 fit into the through-holes 34B, and in consequencethere is no difference in level between fitting surfaces 39A of thefitting blocks 39 and the separating surface 34A and a cylindricalsurface is thereby formed, external surfaces 37A of the base plates 37abut against an internal circumferential wall 34C of the drum 34. Acapability of adhering to the unvulcanized rubber sheet 12 may beimparted to the fitting surfaces 39A by using a material capable ofadhering to the unvulcanized rubber sheet 12 (e.g., iron) to make thefitting blocks 39 themselves, or alternatively, by subjecting thefitting blocks 39 to surface treatment.

The base plates 37 are respectively supported by rods 38 of hydraulicjacks 40, which are respectively fixed to a drum shaft 42 of the drum 34by fixtures (not shown). When the rods 38 are lengthened or shortened,the lifting member 36 is expanded or contracted.

The drum shaft 42 is rotatably supported by shaft supporting members 44.This structure enables the drum 34 to rotate in the direction of ArrowB.

Next, the operation of the second embodiment will be described.

As shown in FIG. 6, when the unvulcanized rubber sheet 12 is stuck, theunvulcanized rubber sheet 12 is supported by the separating surface 34Aof the drum 34 and the fitting surfaces 39A of the lifting member 36without a difference in level being created therebetween. In this state,the unvulcanized rubber sheet 12 is in close contact with the fittingsurfaces 39A of the lifting member 36. Further, the plural fittingsurfaces 39A, where the unvulcanized rubber sheet 12 and the liftingmember 36 make contact with each other, enable the unvulcanized rubbersheet 12 to be held in a stable fashion.

Accordingly, even when the rubber member sticking device 30 is moved ina vertical, longitudinal or widthwise direction, or the drum 34 isrotated in the direction of Arrow B, the unvulcanized rubber sheet 12 isneither removed nor dislocated.

On the other hand, as shown in FIG. 7, when the unvulcanized rubbersheet 12 is separated, the hydraulic jacks 40 pull the lifting member 36inside to create a difference in level between the separating surface34A of the drum 34 and the fitting surfaces 39A of the lifting member 36so that the unvulcanized rubber sheet 12 is supported only by theseparating surface 34A of the drum 34.

In this process, only portions of the unvulcanized rubber sheet 12supported by the fitting surfaces 39A are released first in a state inwhich the remaining portions of the unvulcanized rubber sheet 12continue to be supported by the separating surface 34A. Therefore,deformation and stretching of the unvulcanized rubber sheet 12 occuronly at portions corresponding to the fitting surfaces 39A, and in thisway wholesale deformation and stretching of the unvulcanized rubbersheet 12 can be suppressed. Since the fitting surfaces 39A are dispersedat plural portions, the adhesive force is also dispersed and only arelatively modest force needs to be applied to each of the fittingsurfaces 39A in order to separate it from the unvulcanized rubber sheet12. Deformation and stretching of the unvulcanized rubber sheet 12 canaccordingly be prevented with greater certitude.

Further, since the separating surface 34A has no adhesive property, whenthe unvulcanized rubber sheet 12 is separated from the separatingsurface 34A, the unvulcanized rubber sheet 12 can be transferred andtransported with a modicum of force.

Furthermore, a combination of the rotating movement and the separationoperation enables the unvulcanized rubber sheet 12 to be transferredeasily.

Next, a third embodiment will be described.

Although the third embodiment is basically identical to the secondembodiment, the third embodiment differs from the second embodimentinsofar that a separating surface 54A of a rubber member sticking device50 is provided with plural substantially V-shaped through-holes 54B in aplan view, through-holes 54B being arranged in parallel with each other,as shown in FIG. 8.

A lifting member 56 serving as a second sheet receiving member isdisposed inside a drum 54. The lifting member 56 includes substantiallyV-shaped fitting blocks 59 in a plan view, fitting blocks 59 beingcapable of fitting into/retracting from the through-holes 54B. Externalsurfaces of the fitting blocks 59 are formed as substantially V-shapedfitting surfaces 59A.

In this structure, since the fitting surfaces 59A are respectivelyformed in a substantially V-shape and the fitting surfaces 59A makeclose contact with the unvulcanized rubber sheet 12 (not shown) at acertain angle to the widthwise direction of the unvulcanized rubbersheet 12, the unvulcanized rubber sheet 12 is easily separated from thefitting surfaces 59A.

In the above-described embodiments, in order to separate theunvulcanized rubber sheet, the fitting surfaces are pulled inside.However, the present invention is not limited to this method, and insharp contrast the separating surface may be pushed outside.

Further, in the embodiments described above, hydraulic jacks are used byway of example as a driving means. However, air or electricity may alsobe used as a driving source, and a driving means is not limited tohydraulic jacks.

Furthermore, in the embodiments described above, an unvulcanized rubbersheet is used by way of example as a viscous sheet. However, the presentinvention is not limited to an unvulcanized rubber sheet, and a plasticsheet, for example, may also be used.
